20.500.12556/DKUM-56064 Multivariate data analysis of natural mineral waters Fifty samples of natural mineral waters from springs in Slovenia, Hungary, Germany, Czech Republic and further countries of former Yugoslavia have been analysed. The mass concentration of cations ($Na^+$, $K^+$, $Ca^{2+}$, $Mg^{2+}$, $Fe^{2+}$, $Mn^{2+}$, $NH^+_4$) and anions ($F^-$, $Cl^-$, $I^-$, $NO^-_3$, $SO_4^{2-}$, $HCO_3^-$), the spring temperature, pH, conductivity and carbon dioxide mass concentration have been measured using standard analytical methods. Appropriate statistical methods and different chemometric tools were used to evaluate the obtained data, namely, (i) descriptive statistics, (ii) principal component analysis (PCA), (iii) cluster analysis, and (iv) linear discriminant analysis (LDA). It was confirmed that Slovenian natural mineral water samples differ most from the German ones but are relatively similar to the Czech and Hungarian ones. Water samples from Hungary are similar to waters from the eastern part of Slovenia. Analizirali smo petdeset vzorcev naravne mineralne vode iz izvirov v Sloveniji, na Madžarskem, v Nemčiji, Češki republiki in državah bivše Jugoslavije. Masne koncentracije kationov ($Na^+$, $K^+$, $Ca^{2+}$, $Mg^{2+}$, $Fe^{2+}$, $Mn^{2+}$, $NH^+_4$) in anionov ($F^-$, $Cl^-$, $I^-$, $NO^-_3$, $SO_4^{2-}$, $HCO_3^-$), temperaturo izvira, pH, prevodnost in masno koncentracijo ogljikovega dioksida smo določili z uporabo standardnih analiznih metod. Uporabili smo primerne statistične in kemometrijske metode za evalvacijo podatkov: (i) opisno statistiko, (ii) analizo glavnih komponent (PCA), (iii) analizo klastrov in (iv) linearno diskriminantno analizo (LDA). Potrdili smo, da se slovenske mineralne vode razlikujejo predvsem od nemških in da so sorazmerno podobne češkim in madžarskim. Vzorci vode iz Madžarske so podobni tistim iz vzhodne Slovenije. natural mineral water ion determination principal component analysis cluster analysis linear discriminant analysis naravne mineralne vode določevanje ionov metoda glavnih osi analiza grup linearna diskriminantna analiza true false true Angleški jezik Slovenski jezik Znanstveno delo 2015-12-21 16:23:39 2015-12-21 16:23:39 2022-06-10 03:09:41 2021-05-15 03:27:08 2007 0 0 str. 33-39 št. 1 Letn. 54 2007 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1318-0207 543:331 14086149 11161622 1318-0207 URN:SI:UM:DK:HJ8OWKXG Acta_Chimica_Slovenica_2007_Snuderl_et_al._Multivariate_data_analysis_of_natural_mineral_waters.pdf Acta_Chimica_Slovenica_2007_Snuderl_et_al._Multivariate_data_analysis_of_natural_mineral_waters.pdf 1 5C6822EC348A1A04000D1A85B5D66D91 ef37bf466a91cc66c4efc2d0d7bbac72265e5aefba41fc3973e7985c20980cc5 8d38304f-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=115874 http://acta-arhiv.chem-soc.si/54/54-1-33.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=84197 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
